History of JAVA

Introduction to Java:
Java language” redirects here. For the Indonesian spoken language, see Javanese language.Not to be confused with JavaScript.For other uses, see Java (disambiguation).Java is a programming language originally developed by Sun Microsystems and released in 1995 as a core component of Sun Microsystems’ Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture.
The original and reference implementation Java compilers, virtual machines, and class libraries were developed by Sun from 1995. As of May 2007, in compliance with the specifications of the Java Community Process, Sun made available most of their Java technologies as free software under the GNU General Public License. Others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java and GNU Classpath.


History:
  • Background: Electronic consumer devices
  • Sun commissioned ‘Project Green’
  • Developed language ‘Oak’ -Later renamed to JavaWas dismissed as just another
  • OO programming lang Became popular with the rising popularity of ‘www’

There were five primary goals in the creation of the Java language:[10]

  • It should be “simple, object oriented, and familiar”.
  • It should be “robust and secure”.
  • It should be “architecture neutral and portable”.
  • It should execute with “high performance”.
  • It should be “interpreted, threaded, and dynamic”.

Features of JAVA:

  • Object Oriented
  • Simple
  • Robust
  • Distributed
  • Secure
  • Architecture neutral
  • Portable
  • Interpreted
  • Dynamic
  • Multi threaded
